Well, I should probably stay out of this, but the dialogue so far has piqued my interest.
As an individual who loves accurate rimfires, and has several right now that will shoot
the ½" at 50 M, I have to support grauhanen's take on the subject.
I have not owned nor shot a T1x, so will leave that seemingly exceptional rifle off my
list.
However, I have owned several CZ rifles: 452, 453, 455. All were quite accurate, but
I would never take one to a serious competition, even with ammo they liked.
I have a lot of respect for Anschutz, and own a M54 match HB that shoots better groups
than any of my CZ's could.
Others that outshoot even my Annie are: a Suhl 150 Standard, prepped by Jim Williams,
a 40X Remington HB, and a Model 37 Remington.
A couple of these rifles will shoot .25" at 50 with a certain lot of Eley Match EPS ammo.
Obviously not every groups will be that small, but it shows their capability.
The 40x holds the record 50/50 target here at our club.
